Airworthiness Directives; Embraer S.A. (Type Certificate 
Previously Held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica 
S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Embraer S.A. Model ERJ 190-100 ECJ airplanes. This AD was 
prompted by a determination that new or more restrictive airworthiness 
limitations are necessary and that some life limits on some components 
used on the main landing gear (MLG) may not be properly controlled, due 
to interchanging those parts between airplane models with different 
operational loads during repair or overhaul. This AD requires revising 
the existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations; 
reviewing maintenance records of the MLG assemblies to determine if any 
life-limited item has been replaced and reporting those findings; and 
re-identifying the MLG assemblies and certain components; as specified 
in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, 
which is incorporated by reference. This AD also prohibits installing 
certain part numbers. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective August 31, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 31, 
2022.

SUPPLEMENTARY INFORMATION: 

Background

    ANAC, which is the aviation authority for Brazil, has issued ANAC 
AD 2021-08-01, effective August 31, 2021 (ANAC AD 2021-08-01) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Embraer S.A. Model ERJ 190-100 ECJ airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Embraer S.A. 
Model ERJ 190-100 ECJ airplanes. The NPRM published in the Federal 
Register on April 8, 2022 (87 FR 20787). The NPRM was prompted by a 
determination that new or more restrictive airworthiness limitations 
are necessary and that some life limits on some components used on the 
MLG may not be properly controlled, due to interchanging those parts 
between airplane models with different operational loads during repair 
or overhaul. The NPRM proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations; reviewing maintenance 
records of the MLG assemblies to determine if any life-limited item has 
been replaced and reporting those findings; and re-identifying the MLG 
assemblies and certain components; as specified in ANAC AD 2021-08-01. 
The NPRM also proposed to prohibit installing certain part numbers.
    The FAA is issuing this AD to address potentially inadequate life 
limits on the MLG due to different operational loads, which could 
impact the structural integrity of the airplane. See the MCAI for 
additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from The Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2021-08-01 specifies new or more restrictive airworthiness 
limitations for airplane structures and safe life limits; reviewing 
maintenance records of the MLG side stay assembly and the MLG shock 
strut assembly to determine if any life-limited item has been replaced 
and reporting those findings; and reidentifying certain part numbers of 
the MLG side stay assembly and the MLG shock strut assembly and their 
components. ANAC AD 2021-08-01 also specifies prohibiting the 
installation of certain part numbers. This material is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section.

Interim Action

    The FAA considers this AD interim action. The inspection reports 
required by this AD will enable the manufacturer to gain better insight 
into the extent to which components have been interchanged between 
models and determine if additional actions are required to address the 
identified unsafe condition. Based on the result of the manufacturer's 
analyses, the FAA might consider further rulemaking

Costs of Compliance

    The FAA estimates that this AD affects 10 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate. Therefore, the agency estimates the average total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...........................              $0             $510           $5,100
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting and revising the existing maintenance or inspection
  program.

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, the FAA estimates the 
cost of reporting on U.S. operators to be $850, or $85 per product.
    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
